Title: Crucibleless zone melting generator - cut off by optical fibre signal when sparkover occurs near induction coil
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1979-07-18
Abstract: The high-frequency generator which feeds the induction heating coil in the production of single silicon crystals by crucible-less zone melting is automatically cut off when spark-overs occur in the area of the coil. The light produced by a flash is passed through an optical fibre to a photodiode or phototransistor. Their output signal is amplified and applied to a relay to switch off the h.f. generator. This eliminates false alarms which may be caused by other sensors which also respond to sudden voltage drops or other electrical fluctuations, apart from spark-overs.

Title: Plastic solar heat collector - coated with adhesion activator and pigmented lacquer before metal oxide plating
Inventor: GROSS ERWIN DIPL ING
IPC: F24J2/48
Filed: 1980-02-21
Abstract: Solar heat collectors are best coated with a metal oxide film to absorb a maximum and radiate a minimum of heat. This is easy for metals but impossible for absorbers, made of polypropylene or polyethylene. The difficulty can be overcome by applying first a base coat of a conventional adhesion activator and/or a layer of lacquer on an epoxy or polyester basis. Such a lacquer can be plated with a metal oxide film. The black pigment (carbon black) in the lacquer has a high absorptivity and low radiation losses.

Title: Photovoltaic power supply system - supplies AC mains, using solar generators feeding inverters on bus=bar, coupled to mains commutated inverter
Inventor: NESTLER JOHANNES DR ING
IPC: H02J5/00
Filed: 1980-06-18
Abstract: The photovoltaic power system supplies a.c. or three-phase mains in a process in which solar generators (11-1n) each operate into an inverter (21-2n). Each inverter is in operating connection to a bus-bar (3), to which a mains commutated inverter (4) is coupled, which operates onto alternating or three-phase mains (8). Pref. each solar generator has an additional inverter (91-9n) for the supply of a power accumulator (10). To the latter may be connected a further mains commutated inverter (11), also operating onto the alternating or three-phase mains. An additional inverter (15) may be connected to the accumulator, and operates onto the bus-bar. The process enables application of mains commutated inverters for reactive power reduction. These inverters are of lower cost as compared with automatically commutated inverters, due to application of dynamically more highly loaded thyristors.
Patent DE-3023357-A1 (DE)
Title: Permanent magnet excited D.C. machine - has field pole of 180 degrees electrical arc with armature winding step reduction
Inventor: ALTENBERND GERALD DR ING
IPC: H02K23/04
Filed: 1980-06-23
Abstract: The D.C machine consists of an armature coil (1), armature core (2), and field poles (N,S) the pole pitch spanning the spatial angle of 180 deg./P where P is the number of pole pairs. The electrical angle amounts to 180 degrees and the pole arc (b) of the poles, differs from the pole pitch by a given step reduction (Vz). The coil width (w) of the armature winding is augmented by a step reduction (V1) of the armature winding (1). Commutation in normal D.C machines takes place in the field-free space between poles, therefore a machine whose pole arc is exactly 180 electrical degrees, cannot commutate within this space. Neglecting self inductance, the change in flux must be kept to a min. and with a rectangular shape of the magnetic field, this will be the case as long as the armature coil (1) is revolving into the angle formed by the step reductions (V1 + V2). Commutation takes place inside this angle, and due to the shift of the neutral zone width in the armature, field poles with extreme pole arc can be used without the disadvantages of noise, thermal stress, inherent in conventional machines.
